WATERPROOF FOOTWEAR.

reac es.

To all whom it may canoe Be it known that Josri i i A. AMns, a citizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, has invented certain new and useful Improvements in Waterproof Footwear, of which the following is a specification; This invention relates to water proof foot wear and is particularly directed to an improved method of making such foot wear as well as the article itself.

()ne of the prime objects of my invention is one wherein the foot wear constructed as I have outlined may be readily repaired such as by half soling or by completely soling the goods without in any way interfering with i water-proof properties. In this connect".- u, it may also be understood that my in vention contemplates the combinationof an ordinary rubber upper wlth a leather outer sole or the well known composition equivalent-s of either one or both.

The preferred embodiment of my invention will be better understood In referring to the accompanyingv sheet of rawings in which similar characters of reference designate corresponding parts and in which,

Figures 1 to 6 inclusive represent the various stages of manufacture of my improved article.

In Fig. 1, the ordinary type of insole l is shown which insole is provided with a depending rib of any desired form such as is shown at 2. This structure as shown in Fig. 1 is then preferabl coated with sheet or liquid rubber as is in icated at 3 in Fig. 2 whereupon the upper t as shown in Fig. 3 is applied. Preferably, this upper is worked in along the edges, heel and toe of the insole to pass over the rib 2 as shown at 5 and to overlap at approximately the center of the insole as shown at 6. 'After -the foot wear has been thus built up,--the entire structure is again coated with sheet or liquid rubber as is shown at 7 in Fig. 4. This structure is then placed in a vulcanizing oven and the rubber vulcanized to the desired degree. An entire water proof shell is thus formed and this structure is then ready to receive the welt 8 as shown in Fig. 5. This welt is preferably attached in the well known manner as by stitchest). It will be noted that these stitches do not perforate the shell proper but only pass through its ribbed PIOJBCtlOn. After this, the space between the ribs may Specification of Letters Patent.

be filled with fiber, ground cork or any other desirable substance as indicatedat IQ and the outer sole 11 then applied by stitching through the welt as is shown at 12.

It will thus be observed that an entirely water proof shell is provided onto which an outer sole of any desired material may be applied. This outer sole may also be replaced without injuring the shell and further the upper is protected by the outward projectien of the welt and outer sole against the action of'stones or other objects which ing rubber to at least one surface of said shell to form a continuous coating, vulcanizing,

and then attaching an outer sole.

2. The method of producing water proof footwear which consists in forming an upper around an insole to form a shell, ap

plying rubber to at least one surface of said shell to form a continuous coating, vulcanizing, securing a welt to the structure thus formed, and then attaching an outer sole by means of said welt.

' 3. The method of producing water proof foot Wear which consists in forming an upper around an insole, coating the exterior surface of the assembled structure-of upper and insole with rubber, vulcanizing, and then attachin an outer sole.

4. The met (1 of ,qeni ducing water proof foot wear which consists in coating the bottom of an insole with rubber, forming an upper around the coated insole, coating the exterior surface of the assembled structure of upper and insole with rubber. vulcanizing, securing a welt to thest-fiwture thus formed, and then attaching an outer sole by means of said welt. I

5. The method of producin water proof foot wear which consists in forming an upper around an insole so that the entire bottom of the insole is covered, coating the ex terior surface of the assembled structure of foot wear which consists in iormin upper and insole with rubber, vulcanizing, securing a Welt to the structure thus formed, and then attaching an outer sole by means of said welt.

proof a rib around the. bottom of an insole an covering the bottom of sucl insole and rib with rubber, forming an upper around said insole to lie in engagement with said rib, coating the structure thus far assembled with rubber, vulcani'zing', securing a welt to said rib and. then securing an outer sole to said Welt. r

7-. Water proof foot Wear comprising an inner sole, a rib secured to the bottom of said inner sole and an upper formed around 6. The method of producing water said inner sole, and rib all forming a superstructure, a coating of vulcanized rubber rib, and an outer sole secured to over said superstructure, a welt also carried by said superstructure and secured to said rib, and an outer sole attached to said Welt. I

- ment with said rib all forming a superstructure, a coating of vulcanized rubber over said'superstructure, a Welt secured to said said Welt.

In testimony whereof I aflix my signature in presence of two witnesses.
